BACKGROUND Field of the Disclosure

This disclosure relates generally to information handling systems and more particularly to utilizing document security.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

DETAILED DESCRIPTION

In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are examples and not exhaustive of all possible embodiments.

As used herein, a reference numeral refers to a class or type of entity, and any letter following such reference numeral refers to a specific instance of a particular entity of that class or type. Thus, for example, a hypothetical entity referenced by ‘12A’ may refer to a particular instance of a particular class/type, and the reference ‘12’ may refer to a collection of instances belonging to that particular class/type or any one instance of that class/type in general.

In one or more embodiments, various security methods may attempt to prevent data theft (e.g., data leakage) by policies and/or regulations. For example, there may be no active processes that can detect that a document (e.g., a word processing document, a spreadsheet document, etc.) is being opened in a controlled environment. For instance, if a cyber criminal gains access to a restricted area, the cyber criminal may copy one or more documents and open the one or more documents outside an organization's location (e.g., outside the controlled environment). When documents are taken by a cyber criminal (e.g., data leakage), those documents may be considered “lost causes.” For example, an organization may not have an ability to recover those documents from the cyber criminal, to track those documents, or to prevent dissemination of those documents.

In one or more embodiments, saving a document to a memory medium may be intercepted to add one or more security features within the documents. For example, a call to a write subroutine of an operating system may be intercepted by a security agent. For instance, the security agent may add one or more security features within a document. In one or more embodiments, the one or more security features within the document may include document security executable instructions. For example, the document security executable instructions may ensure that the document may be opened on an information handling system that is authorized to open the document. For instance, if the document is opened on an information handling system that is not authorized to open the document, the document security executable instructions may corrupt data of the document.

Turning now to FIG. 1, an example of an information handling system is illustrated, according to one or more embodiments.

Turning now to FIG. 3, an example of a method of saving a document is illustrated, according to one or more embodiments. At 310, a request to save a document may be instantiated. For example, APP 164 may instantiate a request to OS 162 to save a document 315. In one or more embodiments, a request to save a document may include calling a subroutine of a kernel of an operating system. For example, instantiating a request to save document 315 may include calling a write subroutine 420 of a kernel 410 of OS 162, as illustrated in FIG. 4A.

In one or more embodiments, a plugin may be installed in an operating system that may intercept a write subroutine and/or a read subroutine. For example, a plugin 430 may be installed in OS 162, as shown in FIG. 4B. For instance, plugin 430 may include agent 299. In one or more embodiments, a loadable kernel module may include agent 299. For example, agent 299 may be installed in kernel 410, as illustrated in FIG. 4C. For instance, agent 299 may be or may include a device driver or a pseudo device driver. In one or more embodiments, a loadable kernel module may be a kernel extension. In one or more embodiments, a pseudo device driver may not be associated with a physical device. In one or more embodiments, OS 162 may include the driver. For example, the driver may be or include a loadable kernel module. For instance, when OS 162 loads the loadable kernel module, the loadable kernel module may direct or redirect requests to save documents.

At 320, the request to save the document may be intercepted. For example, a subroutine may intercept the request to save document 315. For instance, a request to save document 315 may include a call to a subroutine to write document 315 to a memory medium. In one or more embodiments, a write subroutine 422 of agent 299 may intercept the call to write subroutine 420 to write document 315 to a memory medium, as shown in FIG. 4D.

At 330, a signature associated with the information handling system may be generated. For example, a signature associated with IHS 110A may be generated. For instance, agent 299A may generate the signature associated with IHS 110A. In one or more embodiments, generating a signature associated with IHS 110A may include determining one or more identifiers of respective one or more components of IHS 110A. For example, the one or more components of IHS 110A may include one or more of processor 120, GPU 140, volatile memory medium 150, non-volatile memory medium 160, non-volatile memory medium 170, network interface 180, a keyboard, and a pointing device (e.g., a mouse, a touchpad, etc.), among others. For instance, the one or more identifiers of respective one or more components of IHS 110A may include one or more of a processor identifier of processor 120, a GPU identifier of GPU 140, a display identifier of a display, a volatile memory medium identifier of volatile memory medium 150 (e.g., a RAM part number), a first non-volatile memory medium identifier of non-volatile memory medium 160, a second non-volatile memory medium identifier of non-volatile memory medium 170, a network interface identifier of network interface 180, an IHSFW identifier of IHSFW 172, a VPN identifier of a VPN connection, a keyboard identifier of the keyboard, and a pointing device identifier of the pointing device. In one or more embodiments, one or more identifiers may include one or more network addresses. In one example, a network address may include a media access control address (MAC) address. In a second example, a network address may include an Internet protocol (IP) address. In another example, an identifier of a domain name service (DNS) server (e.g., an IP address of a DNS server).

At 340, document security executable instructions for the document may be created. For example, document security executable instructions 345 may be created for document 315. For instance, agent 299 may create document security executable instructions 345 for document 315. In one or more embodiments, document security executable instructions 345 may be executable by APP 164. In one or more embodiments, document security executable instructions 345 may include instructions executable by processor 120, may include a script, and/or may include source code that may be compiled and executed by processor 120 and/or executed by a virtual machine.

At 350, the document security executable instructions for the document may be added to the document. For example, document security executable instructions 345 may be added to document 315. For instance, agent 299 may add document security executable instructions 345 to document 315. In one or more embodiments, document security executable instructions 345 may be added anywhere within document 315. In one example, document security executable instructions 345 may be added at a first number of bytes from a beginning of document 315. In a second example, document security executable instructions 345 may be added at a second number of bytes before an ending of document 315. In a third example, document security executable instructions 345 may be added within document data 316. In a fourth example, document security executable instructions 345 may be interleaved in document data 316. In a sixth example, document security executable instructions 345 may be an image within document 315. In another example, document security executable instructions 345 may be at an end of a body of document 315. In one or more embodiments, a body of document 315 may include document data 316.

At 360, a hash value of the signature of the information handling system and the document may be determined. For example, a hash value 355 of the signature of IHS 110A and document 315, which includes executable instructions 345, may be determined. For instance, determining hash value 355 of the signature of IHS 110A and document 315 may include utilizing the signature of IHS 110A and document 315 as input to a one-way hash function.

In one or more embodiments, a one-way hash function may be considered collision free. For example, the one-way hash function may be injective or one-to-one. For instance, h(z₁) and h(z₂) may produce different values, where inputs z₁ and z₂ are different. In one or more embodiments, a one-way hash function may be considered a cryptographic checksum, a message digest, a digital fingerprint, a message integrity check, a contraction function, a compression function, and/or a manipulation detection code, among others. Examples of one-way hash functions may include one or more of an Abreast Davies-Meyer, a Davies-Meyer, a message digest (MD) 2, a MD 4, a MD 5, a RIPE-MD, a GOST Hash, a N-HASH, a HAVAL, a SHA (secure hash algorithm) (e.g., SHA-1, SHA-2, SHA-3, SHA-256, SHA-384, etc.), and a SNEFRU, among others. In one or more embodiments, a one-way hash function may be a composite function of two or more one-way hash functions. For example, a function h₁ may include a MD 5 one-way hash function h₂, a SHA one-way hash function h₃, and a MD 5 one-way hash function h₄, such that h₁=h₂(h₃(h₄(z))). For instance, a one-way hash function that is a composite function of two or more one-way hash functions may be considered to be and/or said to be strengthened.

At 370, the hash value may be stored in the document. For example, hash value 355 may be stored in document 315. For instance, agent 299 may store hash value 355 in document 315. In one or more embodiments, the hash value may be encrypted via an encryption key. For example, the hash value may be encrypted via a private encryption key to create a digital signature of the signature of the information handling system and the document. For instance, the digital signature may be stored in the document in addition to or in lieu of the hash value. In one or more embodiments, a public encryption key, associated with the private encryption key, may be utilized to recover or obtain the hash value.

At 380, the document may be store via a memory medium. In one example, document 315 may be stored via non-volatile memory medium 160 of IHS 110A. In another example, storing the document may be store via a memory medium may include storing the document via an information handling system coupled to a network. For instance, document 315 may be stored via non-volatile memory medium 160 of IHS 110E. In one or more embodiments, IHS 110A may provide document 315 to IHS 110E via network 220, and IHS 110E may receive document 315 and store document 315 via non-volatile memory medium 160 of IHS 110E.

In one or more embodiments, storing the document via the memory medium may include the subroutine providing document 315, with its additions, to a portion of OS 162 that would have saved document 315 before the subroutine intercepted the request to save document 315. For example, agent 299 may provide document 315, with its additions of document security executable instructions 345 and hash value 355, to write subroutine 420, as illustrated in FIG. 4D. For instance, agent 299 may call subroutine 420. In one or more embodiments, write subroutine 420 may write document 315, with its additions of document security executable instructions 345 and hash value 355, to a memory medium.

Turning now to FIGS. 5A and 5B, an example of a method of utilizing a document with document security instructions is illustrated, according to one or more embodiments. As shown, IHS 110A and IHS 110D may access document 315. In this example process, IHS 110A may be able to access data 316 of document 315, while IHS 110D may not be able to access data 316 of document 315. At 520, it may be determined that a system read call was instantiated. For example, APP 164 may determine that a system read call was instantiated.

At 525, the instructions added to the document may be executed. For example, document security executable instructions 345 may be executed. In one instance, APP 164 may execute document security executable instructions 345. In another instance, processor 120 may execute document security executable instructions 345. In one or more embodiments, APP 164 may instruct processor 120 to execute document security executable instructions 345.

At 530, it may be determined if a security agent exists on the information handling system. For example, document security executable instructions 345 may determine if a security agent 299 exists on IHS 110. For instance, document security executable instructions 345 may query OS 162 to determine if security agent 299 exists on IHS 110.

If the security agent does not exist on the information handling system, the data of the document may be corrupted, at 535. For example, security agent 299C may not exist on IHS 110D. If the security agent does not exist on IHS 110D, document security executable instructions 345 may corrupt data 316. In one example, data 316 may include word processing data (e.g., a letter, a report, a contract, a chapter of a book, a book, a play, a screen play, etc.). In a second example, data 316 may include spreadsheet data. In a third example, data 316 may include graphics data (e.g., jpeg graphics data, Photoshop graphics data, Visio drawing data, etc.). In a fourth example, data 316 may include audio data (e.g., sound data). In another example, data 316 may include video data (e.g., motion image data).

In one or more embodiments, corrupting data 316 may include overwriting data 316. In one example, corrupting data 316 may include overwriting data 316 with a single byte (e.g., writing the single byte to all bytes of data 316). In another example, corrupting data 316 may include overwriting data 316 with multiple bytes (e.g., writing a string of bytes to data 316). In one instance, the multiple bytes may be repeatedly written over one or more portions of data 316. In another instance, the multiple bytes may be random bytes, which may be written over one or more portions of data 316.

If the security agent does exist on the information handling system, a signature of the information handling system may be generated, at 540. In one or more embodiments, method element 540 may be performed in a similar or same fashion as method element 330. In one example, security agent 299A may generate a signature of IHS 110A. In another example, IHS 110D may include agent 299D, and security agent 299D may generate a signature of IHS 110D.

At 545, a hash value of the signature of the information handling system and the document may be determined. For example, a hash value 550 of the signature of IHS 110A and document 315, which includes document security executable instructions 345, may be determined. For instance, security agent 299 may determine hash value 550. At 555, it may be determined if the hash value of the signature of the information handling system and the document match the hash value stored in the document. For example, it may be determined if hash value 550 matches hash value 355. For instance, security agent 299 may determine if hash value 550 matches hash value 355.

In one or more embodiments, a signature of IHS 110A may not match a signature of IHS 110D. If the signature of IHS 110A does not match the signature of IHS 110D, a hash value of the signature of IHS 110A and document 315 may not match a hash value of the signature of IHS 110D and document 315. In one or more embodiments, a first signature of IHS 110A may not match a second signature of IHS 110A. For example, an identifier associated with IHS 110A may have changed since hash value 355 was determined. If the first signature of IHS 110A does not match the second signature of IHS 110A, a first hash value of the first signature of IHS 110A and document 315 may not match a second hash value of the second signature of IHS 110A and document 315.

If the hash value of the signature of the information handling system and the document does not match the hash value stored in the document, the process may proceed to 535. For example, if hash value 550 does not match hash value 355, the process may proceed to 535. If the hash value of the signature of the information handling system and the document does match the hash value stored in the document (e.g., hash value 550 does match hash value 355), the data of the document may be provided to the application, at 560. For example, data 316 of document 315 may be provided to APP 164. In one instance, security agent 299 may permit OS 162 to provide data 316 of document 315 to APP 164. In another instance, document security executable instructions 345 may permit OS 162 to provide data 316 of document 315 to APP 164.

Turning now to FIGS. 5C and 5D, a second example of a method of utilizing a document with document security instructions is illustrated, according to one or more embodiments. As shown, document 315 may include multiple hash values 355A-355C. For example, hash values 355A-355C may be respectively associated with IHSs 110A-110C. Method elements 520-545, 555, and 560 of FIGS. 5C and 5D may be performed as method elements 20-545, 555, and 560 are described with reference to FIGS. 5A and 5B.

In one or more embodiments, method element 555 may be performed for each hash value of multiple hash values of document 315 or until a hash value of the signature of the information handling system and the document match a hash value stored in the document. For example, method element 555 may be performed for each hash value 355 of hash values 355A-355C or until hash value 550 matches one of hash values 355A-355C. If hash value 550 matches a hash value of hash values 355A-355C, the method may proceed to 560. If hash value 550 does not match a hash value of hash values 355A-355C, it may be determined if there is another hash value stored in document 315, at 557. If there is another hash value stored in document 315, the method may proceed to 555. If there is not another hash value stored in document 315, the method may proceed to 535. As an example, if the method illustrated in FIGS. 5C and 5D is performed on an IHS of IHSs 110A-110C, the method may proceed to 560. As another example, if the method illustrated in FIGS. 5C and 5D is performed on IHS 110D, the method may proceed to 535.

Turning now to FIG. 6, another example of a method of utilizing a document with document security instructions is illustrated, according to one or more embodiments. At 610, a document may be read. For example, APP 164 may read document 315. At 615, it may be determined that the document includes document security executable instructions. For example, APP 164 may determine that document 315 includes document security executable instructions 345.

At 620, the document security executable instructions of the document may be executed. In one example, APP 164 may execute document security executable instructions 345 of document 315. In another example, processor 120 may execute document security executable instructions 345 of document 315. At 625, it may be determined if a security agent exists on an information handling system. For example, APP 164 may determine if security agent 299 exists on IHS 110.

If the security agent does not exist on the information handling system, data of the document may be corrupted, at 630. For example, if security agent 299 does not exist on IHS 110, APP 164 may corrupt data 316 of document 315. If the security agent does exist on the information handling system, an array of bytes associated with multiple identifiers of multiple components of the information handling system may be generated, at 635. For example, if security agent 299 does exist on IHS 110, security agent 299 may generate an array of bytes associated with multiple identifiers of multiple components of IHS 110. In one or more embodiments, generating the array of bytes associated with the multiple identifiers of the multiple components of the information handling system may include combining the multiple identifiers of the multiple components into the array of bytes.

At 640, a first hash value of the array of bytes and the document may be determined. For example, security agent 299 may determine hash value 550 of the array of bytes and document 315. At 645, a second hash value may be retrieved from the document. For example, security agent 299 may retrieve hash value 355 from document 315.

At 650, it may be determined if the first hash value matches the second hash value. For example, security agent 299 may determine if hash value 550 matches hash value 355. If the first hash value does not match the second hash value, the data of the document may be corrupted, at 655. In one example, security agent 299 may corrupt data 316 of document 315. In another example, document security executable instructions 345 may corrupt data 316 of document 315. For instance, security agent 299 may instruct document security executable instructions 345 to corrupt data 316 of document 315. If the first hash value does match the second hash value, the data of the document may be provided to the application, at 660. For example, security agent 299 may provide data 316 of document 315 to APP 164. For instance, security agent 299 providing data 316 of document 315 to APP 164 may include permitting OS 162 to provide data 316 of document 315 to APP 164.

Turning now to FIG. 7, another example of a method of saving a document is illustrated, according to one or more embodiments. At 710, it may be determined that an operating system subroutine to save a document has been instantiated by an application executing on an information handling system. For example, security agent 299 may determine that an operating system subroutine to save document 315 has been instantiated by APP 164 executing on IHS 110. For instance, an operating system subroutine to save a document may include an operating system subroutine to write a document to a memory medium. In one or more embodiments, determining that an operating system subroutine to save a document has been instantiated by an application may include intercepting a call to the operating system subroutine to save the document.

At 715, the document may be received. For example, security agent 299 may receive document 315. In one or more embodiments, receiving the document may be performed in response to determining that operating system subroutine to save the document has been instantiated. At 720, an array of bytes associated with multiple identifications of multiple components of the information handling system may be generated. For example, security agent 299 may generate an array of bytes associated with multiple identifications of multiple components of IHS 110. In one or more embodiments, generating the array of bytes associated with the multiple identifiers of the multiple components of the information handling system may include combining the multiple identifiers of the multiple components into the array of bytes.

At 725, document security executable instructions may be added to the document. For example, security agent 299 may add document security executable instructions 345 to document 315. At 730, a hash value of the array of bytes and the document may be determined. For example, security agent 299 may determine hash value 355 of the array of bytes and document 355.

At 735, the hash value may be added to the document. For example, security agent 299 may add hash value 355 to document 315. At 740, the operating system subroutine may be permitted to save the document with its additions of the document security executable instructions and the hash value. For example, security agent 299 may permit the operating system subroutine to save document 315 with its additions of document security executable instructions 345 and hash value 355.

In one or more embodiments, one or more of the method and/or process elements and/or one or more portions of a method and/or a process element may be performed in varying orders, may be repeated, or may be omitted. Furthermore, additional, supplementary, and/or duplicated method and/or process elements may be implemented, instantiated, and/or performed as desired, according to one or more embodiments. Moreover, one or more of system elements may be omitted and/or additional system elements may be added as desired, according to one or more embodiments.

In one or more embodiments, a memory medium may be and/or may include an article of manufacture. For example, the article of manufacture may include and/or may be a software product and/or a program product. For instance, the memory medium may be coded and/or encoded with processor-executable instructions in accordance with at least a portion of one or more flowcharts, at least a portion of one or more systems, at least a portion of one or more methods, and/or at least a portion of one or more processes described herein to produce the article of manufacture.
